Title: Distributor for fluid coaxial pipes - has central connection for centre pipe part hermetically sealed by cap and sealing ring
Inventor: WOLF FRANZ JOSEF
IPC: F16L39/00
Filed: 1991-06-27
Abstract: A radially cut end section (1) of the pipe is connected to a sleeve-like distributor member (2) so that a central divided pipe (20) is tightly connected inside a housing (3) to a central connecting element (21) of the distributor member (2). At least one output connection (22) is in fluid communication with the output side whilst an outer cylindrical pipe part (26) of the coaxial pipe opens around the connecting element (21) for the central pipe part freely into a ring chamber (16) which is also formed inside the housing (3) of the distributor. The coaxial pipe is enclosed on its outer sleeve with sealing tension by an elastic sealing ring (4). The elastic ring is pressed axially by a lockable cap (5) on the rear open end of the housing onto the end edge (18) of this open end so that the ring space (16) inside the distributor into which the outer cylindrical pipe part opens, is hermetically sealed. USE/ADVANTAGE - The distributor can be made from three parts, namely two injection moulded mass-produced parts and a simple rubber moulded part.

Inventor: STAUDACHER OTTO
IPC: E04B2/18
Filed: 1991-08-24
Abstract: For the further improvement of the thermal insulation capacity of a brick, it is proposed that the latter consists of a plurality of linked partial bricks (1, 2) which are separated from one another by gaps (4, 5, 6, 8, 9) running substantially parallel to the exposed faces (7). The loose connection of the partial bricks (1, 2) can be brought about by undercut grooves, in particular dovetail grooves, running in the vertical direction, and projections (3) which are adapted to the groove cross-section and engage in the grooves.

Title: Direction detection in crossed-beam laser Doppler velocimetry using Brillouin frequency shift - using two or more laser beams with frequency shifts forming measurement volume with moving strip system
Inventor: DOPHEIDE DIETRICH DR
IPC: G01P13/04
Filed: 1991-09-14
Abstract: The method of direction detection involves using at least two laser beams with shifted light frequencies which form a measurement vol. with a moving strip system as a scale in their penetration region.
